In the Bass Coast town of Wonthaggi, JNB Concrete took on a project that perfectly exemplifies our commitment to crafting functional and aesthetically pleasing concrete structures. Our task was to construct an extension concrete slab with a distinctive burnt finish, seamlessly blending practicality and visual appeal.

This project demanded a unique approach and an understanding of materials and finishes that would not only enhance the space but also withstand the test of time.

Client: Residential

Location: Wonthaggi

Services: Double Steel Extension Slab


One of the notable challenges of this project was the need for exceptional durability. The extension concrete slab was intended to serve as a robust and long-lasting addition to the property. To achieve this, we decided to set the concrete in double steel reinforcement. This was a strategic choice to ensure the slab’s structural integrity, making it capable of withstanding heavy loads and resisting wear and tear over the years. Our team’s expertise in selecting the appropriate reinforcement was critical in meeting this challenge.

The standout feature of this project was undoubtedly the burnt finish applied to the concrete slab. This unique and eye-catching finish involves a deliberate process of burning the concrete’s surface to achieve a distinctive texture and appearance. The burnt finish not only adds character to the slab but also enhances its resistance to external factors like weather and abrasion.

Setting the concrete in double steel reinforcement was a crucial step in ensuring the slab’s longevity and strength. This method involved placing two layers of steel mesh or rebar within the concrete, providing exceptional reinforcement. The double steel reinforcement not only enhances the slab’s load-bearing capacity but also minimizes the risk of cracking and structural damage.

The burnt finish, on the other hand, is an artful touch that requires precision and expertise. It involves exposing the concrete surface to high temperatures, typically through controlled flames or torching. This process creates a unique texture and appearance, with variations in colour and pattern that give the concrete a distinct character. Importantly, the burnt finish also enhances the concrete’s durability, making it more resistant to moisture, stains, and daily wear.

In conclusion, our project in Wonthaggi showcased our ability to tackle unique challenges in concrete construction while delivering a visually striking and durable solution. The combination of double steel reinforcement and the burnt finish not only ensured the slab’s strength but also added a touch of individuality and resilience to the extension. This project stands as a testament to our dedication to craftsmanship, innovation, and client satisfaction.
